Definitions
- This invention relates to the process of using resident microorganisms to change the oil-water relative permeability of oil field reservoirs. More particularly this invention contemplates a method of manipulating resident microorganisms in an oil reservoir through nutrient stimulation and then nutrient limitation. This manipulation thereby improves oil production rate and estimated ultimate recovery (EUR) from the oil reservoir by changing the oil-water relative permeability of the reservoir to a more oil permeable condition.
- This manipulation thereby improves oil production rate and estimated ultimate recovery (EUR) from the oil reservoir by changing the oil-water relative permeability of the reservoir to a more oil permeable condition.
- EURO estimated ultimate recovery
- An objective of the present invention is to provide a method that changes oil-water relative permeability of oil field reservoirs.
- Another objective of the present invention is to provide a method of modifying resident microorganisms in an oil reservoir through nutrient stimulation and limitation to improve oil production rates and estimated ultimate recovery from the oil reservoir.
- a method of increasing oil recovery from oil reservoirs includes the step of conducting a series of lab analysis that lead to a specific nutrient formulation followed by or in parallel with a genetic analysis of resident microorganisms in water produced from an oil reservoir to determine if oil interactive microorganisms may be modified to produce a change in oil-water relative permeability of an oil reservoir.
- the series of analyses are conducted to determine the contents of a specific nutrient formulation package to optimize changes in the resident microorganisms to enhance oil recovery by changing oil-water relative permeability in the oil reservoir.
- the specific nutrient formulation is applied to stimulate some of the resident microorganisms to interact with oil contained in the reservoir rock formations.
- the stimulation step is followed by limiting the specific nutrient formation to alter or modify the physiology and surface characteristics of the targeted microorganisms.
- Disclosed is a method to increase oil recovery from oil reservoirs of all types including, but not limited to, sandstone, carbonate, conglomerate, shale, siltstone or other rock-type.
- the method modifies the population of resident microorganisms found in an oil reservoir.
- the method of modifying the resident microorganisms is accomplished by applying a specific nutrient formulation to stimulate some of the resident microorganisms to interact with the oil contained in the reservoir rock formation.
- the nutrient is an organic digest or extract of protein and/or a cell extract of prokaryotic or eukaryotic cells.
- the nutrients are not derived from sugars (for example molasses).
- the step of stimulation of targeting resident microorganisms is followed by specific sunrient limitation that alters the physiology and surface characteristics of the targeted microorganisms. This cycle of nutrient supplementation and limitation may be repeated.
- this modification of the resident microorganisms includes changes in size or hydrophobic properties that alter surface-active properties. Typical reductions in microorganism cell volume are 50% or more.
- the step of stimulation and modification of the surface oil interactive properties of the resident microorganisms is to a level, which enhances oil recovery.
- These surface-active properties are such that the interfacial tension and associated relative oil-water relative permeability are changed.
- a specific package of nutrients in a liquid form that can be diluted to produce a range of concentrations from 100 grams per liter to 0.0001 grams per liter in the treated volume.
- Specific packages of nutrients facilitate microbe-mediated oil release in reservoirs where biological life occurs.
- specific nutrient formulations facilitate microbe-mediated oil release in reservoirs up to 130 C and 150,000 ppm total dissolved solids (TDS).
- the method uses a series of analyses that lead to formulation of a specific nutrient package to perform a microbiological response analysis under actual reservoir conditions of the resident population of microorganisms with the intent of refining the treatment of a reservoir to optimize changes in the resident microorganisms that enhance the recovery of oil though altered oil-water relative permeability.
- the nutrient formulation stimulates desirable resident microorganisms and suppresses some undesirable resident microorganisms.
- the delivery of the nutrient package occurs via both water injection wells and producing wells.
- the method also uses genetic analysis of resident microorganisms in produced water to aid in the determination of the presence of the oil interactive microorganisms with the intent of altering oil-water relative permeability.
- Charts 1 to 3 show the oil production improvement by increasing the saturation of oil within the treated pore space and moving to a more favorable position on the relative oil-water permeability curve to create a situation more favorable for oil production and recovery.
- Resident Microorganisms are defined as microorganisms that occur in oil reservoirs, prior to the envisioned treatment, irrespective of the microorganism's origin or where they occur within the oil-bearing strata.
